Kev siv cov khoom hnyav thiab cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, kev siv cov khoom zoo nkauj, cov khoom siv roj hmab, cov twj siv twj paj nruag, thiab cov khoom siv hluav taws xob.
Nyob rau hauv lub nylon ntxiv iav fiber, toughening tus neeg sawv cev thiab lwm yam blends ntawm mechanical thaj chaw. Cov kev tshwm sim qhia tau hais tias nrog cov ntsiab lus ntawm cov iav fiber ntau, lub zog tensile thiab flexural lub zog ntawm cov khoom nce heev, feem zog muaj ntau dua, tus toughening tus neeg mob ntxiv, lub toughness ntawm cov khoom loj heev. Ntxiv 30% ~ 35% iav fiber ntau, 8% ~ 12% toughening agent, qhov zoo tshaj plaws cov khoom siv cov khoom.
1. GFR-nylon Nyob hauv cov nylon resin los ntawm kev ntxiv ib qho ntawm cov iav fiber reinforced yas (FR-PA). Yuav muab faib ua cov hlua khov ntev ntev (fiber ntau thiab cov khoom yas, feem ntau ntawm 10 hli) thiab tis fiber ntau los ntawm nws, los yog txuas ntxiv fiber ntau rau hauv tus ntxaib ntswj extruder nruam sib tov Luv iav fiber reinforced nylon (iav fiber ntau ntawm 0.2 ~ 0.7mm).
2. Nylon yog ib tug polyamide nrog cov amino pawg hauv nws lub ntsiab muag. Amino pawg yog hnyav ncos thiab nyiam txhua yam vim kev sib txuas ntawm hydrogen. Yog li ntawd, nylon yog yooj yim rau crystallize thiab ua tau rau hauv siab zog fibers. Polyamide horny translucent translucent translucent los yog milky dawb crystalline cob, feem ntau yog ua los ntawm cylindrical pellets, yas siv rau cov nyhuv rau polyamide molecular feem ntau yog 15,000 rau 20,000.
3. PA ntxiv 30% iav fiber ntau, PA66 cov khoom siv dag zog, dimensional stability, tshav kub ua haujlwm, los tiv thaiv kev laus muaj zog tuaj yeem kho qis zog tsis tau kho kom zoo dua 2.5 zaug.
4. Cov ntaub ntawv muaj zog los txhim kho cov nylon, cov ntaub ntawv muaj zog yog cov iav fiber, fiber ntau asbestos, carbon fiber, titanium, thiab lwm yam, uas cov iav tseem ceeb ua kom cov nylon kub hnyiab, dimensional stability, rigidity, mechanical properties (stretching Strength thiab khoov zog), tshwj xeeb tshaj yog, txhawm rau txhim kho cov khoom siv dag zog, qhov kev kawm zoo ntawm cov khoom siv hlau. Cov iav fiber reinforced nylon tau ntev fiber reinforced thiab luv fiber ntau reinforced nylon 66 ob. Lub tuam txhab nyob hauv:
